Measurement Trains & Systems
Train Monitoring
Comprehensive inspections detect safety issues like onboard fires or irregular train shapes.
Train Profile
Train integrity must be monitored before entering tunnels to prevent accidents caused by protruding objects, which pose risks to passengers and infrastructure. The system uses laser technology with a high sampling rate to detect gauge interference, coupled with traditional video surveillance to capture a sequence of digital images of the train. This combination ensures the timely identification of any faults or objects that could affect safety.
The system captures the train’s 3D profile using laser triangulation and high-resolution cameras at speeds up to 300 km/h. An algorithm processes the data, comparing it with UIC 505 thresholds to detect irregular shapes exceeding the allowed clearance area.
The system measures the train gauge at any speed, using lasers and cameras to monitor exceedances. It visualizes issues in reports and a graphical interface, and can be used for both single and double track inspections.

Train Temperature: Thermographic Scanning
Hot axle boxes or burning loads must be detected before entering tunnels to prevent disasters. A thermal camera creates a thermal map, but accurate temperature evaluation requires consideration of material emissivity, surface roughness, and viewing angle. MERMEC’s advanced scanner uses specialized sensors to create a precise thermal map, identifying temperature anomalies across the train’s surface.

Pantograph Parameters
The interaction between the pantograph and the catenary is influenced by various internal and external factors that affect the system’s dynamic behavior, leading to parameter variations. A pantograph in non-standard conditions can damage the contact line or require specific maintenance. Therefore, a complete inspection of all pantograph components is necessary for accurate data correlation.
The Morph & Wear module performs 3D measurements of the pantograph using a laser beam and digital camera. It identifies shape defects in the pantograph head by comparing with 3D models or previous scans, and measures wear on the contact strip for material loss.
This unit captures a color image of each pantograph, combined with data from other modules. It uses a color scan camera with infrared illumination, safe for the eyes, activated at night. Nighttime images appear in grayscale.
The Y-Tension Module measures the contact wire’s vertical position during pantograph transit to determine pressure. Data is captured when the train enters the monitored area and saved for a predefined time span before and after the pantograph passes.
The LineScan module captures high-speed, high-resolution images of the contact shoe’s upper surface, automatically identifying the material and detecting cracks.

Brake Parameters
Brakes are designed to wear out, but monitoring wear rates is essential to maximize brake life and prevent failures from inefficient interaction with the wheels, which can cause damage. Tracking wear trends enables predictive maintenance. The rail wheel and brake interaction are crucial for the safety and quality of railway transport.
The system measures brake pad wear on both incoming and outgoing trains, providing data for maintenance planning. It compares measured parameters to tolerance thresholds, sending alarms for unusual conditions. It features two configurations for lining (L) and shoe (S) acquisitions, covering various brake pad positions.
The brake disk wear is monitored using a high-speed laser-camera triangulation system, which analyzes the wear status and distribution. The system compares measurements to tolerance thresholds and provides performance trends and predictive maintenance insights.
The system monitors brake shoe wear using image processing of pictures acquired by a detection system. The processing software analyzes the parameters, compares them to tolerance thresholds, and provides performance trends and predictive maintenance insights.

Wheel Parameters
Wheels face high mechanical stress, affecting running behavior and comfort. Regular inspections are crucial for operational reliability. Wheel inspections must detect both surface and internal flaws, similar to rail track assessments, ensuring safe and efficient performance.
